In the Krasnodar Territory, on the experimental field of the Krasnodar Research Centre for Animal Husbandry and Veterinary Medicine, an experiment was conducted to determine the effect of a new complex biofertilizer on the yield and biometric indicators of a vetch-triticale fodder grass mixture. The conducted experiment shows that with the use of a new complex bio-fertilizer, an increase in the density of planting is observed in triticale (by 16 pieces or by 24%) and in Glinkovskaya vetch by (15 pieces or by 30%). Empirically, it was found that it is best to cultivate vetch-triticale grass mixtures for livestock feed with varieties of Hungarian vetch, in particular with the Orlan variety, since this variety showed a greater increase in green mass both in the experimental and in the control variant. It was also found that the use of a new bio-fertilizer has a positive effect on the overall agrochemical characteristics of the soil, improving and enriching its composition.
